[0002] An inverter is a converter that converts DC power into constant frequency and voltage or frequency and voltage-regulated AC power. Wall-mounted inverters are usually photovoltaic inverters. Because of their small size and light weight, they can be wall-mounted. Generally speaking, wall-mounted inverters can be installed indoors or outdoors.

[0003] According to the installation specifications for wall-mounted inverters, when installed outdoors, a rain and sun shed needs to be installed above the inverter to avoid direct sunlight and rain soaking, and the inverter should not be directly exposed to the sun or other heat sources. The requirements in the specifications are mainly to prevent the inverter from being eroded by rain and high temperature causing accelerated aging of parts.

[0004] However, the existing wall-mounted inverters available on the market are often a single body. The inverter usually does not come with the rain and sun shed mentioned in the installation specifications. Instead, the user is required to customize the shed according to the specifications of the inverter and take corresponding sun protection measures.

[0005] To this end, in view of the defects of the above-mentioned wall-mounted inverter in use, those skilled in the art have proposed a technical solution of a wall-mounted inverter with a sunshade and rainproof canopy structure. Utility Model Content

[0029] Example

[0030] Description of the wall-mounted back frame assembly and sunshade awning assembly on the back of the wall-mounted inverter:

[0031] Refer to the instruction manual Figure 3 and attached Figure 4 As shown;

[0032] This embodiment includes: a wall-mounted back frame assembly.

[0033] The utility model comprises an inverter body 1 and a wall-mounted back frame assembly 2 arranged on the back surface of the inverter body 1 .

[0034] The wall-mounted back frame assembly 2 includes an aluminum alloy bracket 21, side connecting plates 22 fixed on both sides of the aluminum alloy bracket 21, and a connecting plate 24 fixed to the wall. Two internal threaded sleeves 26 that cooperate with the screws on the side connecting plate 22 are fixed on one side of the connecting plate 24 close to the side connecting plate 22.

[0035] The front side wall of the aluminum alloy bracket 21 is fixedly connected to the back surface of the inverter body 1 by screws; a threaded hole is provided on one side of the side connecting plate 22 close to the connecting plate 24, and a screw adapted to the internal threaded sleeve 26 is arranged in the threaded hole.

[0036] A protrusion 25 is fixed on the middle side wall of the connecting plate 24, and an expansion screw drilled into the wall is arranged inside the protrusion 25; two beams 23 are fixed between the sides of the connecting plates 24 that are close to each other, and a plurality of round holes for lightweighting are opened inside the beams 23.

[0037] Refer to the instruction manual Figure 2 and attached Figure 4 As shown;

[0038] This embodiment also includes: a sunshade awning component.

[0039] A sunshade and rain shelter assembly 3 is fixed on the side wall of the wall-mounted back frame assembly 2 to shield the top area of ​​the inverter body 1.

[0040] The sunshade awning assembly 3 includes an I-shaped plate 31, a metal plate 35 fixed on the top of the I-shaped plate 31, and bevel plates 36 fixed on the left and right sides of the metal plate 35, and the other end of the bevel plate 36 is inclined downward.

[0041] The back surface of the I-shaped plate 31 is fixedly connected to the front side wall of the cross beam 23 ; two support rods 32 are connected between the front side wall of the I-shaped plate 31 and the bottom surface of the metal plate 35 for reinforcing the stability of the metal plate 35 .

[0042] A sound insulation layer 33 is fixed on the bottom surface of the metal plate 35 to reduce the noise generated by the collision of rainwater and the metal plate 35; it is worth noting that the sound insulation layer 33 can be replaced by a heat insulation material, or both, and a heat insulation material is laid on the lower surface of the sound insulation layer 33 to isolate the heat brought by the sun. Two rain gutters 34 are fixed on the front side wall of the metal plate 35 to guide the rainwater on the top of the metal plate 35.

[0043] Specifically, the bevel plates 36 on both sides of the metal plate 35 are tilted downward at one end, thereby guiding rainwater on the upper surface of the metal plate 35 to flow downward, and the two sides of the inverter can be wrapped and shielded by tilting.

[0044] At the same time, the rain gutter 34 at the front section of the metal plate 35 can also guide the top rainwater, and cooperate with the bevel plate 36 to make the surface of the metal plate 35 have as little rainwater as possible. Moreover, the metal plate 35 can be designed to be slightly inclined toward the front end to facilitate the discharge of rainwater.

[0045] Finally, if the inverter is a type with air inlet and outlet from top to bottom, the height of the metal plate 35 needs to be maintained at a range of 50 cm above the top of the inverter, and the overall area of ​​the metal plate 35 needs to be increased accordingly. On the contrary, if the inverter is a type with air inlet and outlet from left to right, the height of the metal plate 35 should be maintained between 4 cm and 15 cm.
